Турнир "ФБ-6" -> Tournament "The Final Battle - 6"

All players will have the same number of matches, but the number of games will likely be different. Based on this, criteria based on match results seem more important than those based on game results.
Therefore, I suggest making the third of the four additional criteria the first.

Yes, you are probably right. I will prioritize KB in matches. If there are any other considerations regarding the criteria, please write them down, and we will discuss them.
Ideally, if all matches are played to 2 wins, the criterion "more wins in games" will also not work.
I spent a long time working with the table, substituting numbers... I tried to simulate possible situations with withdrawals and incomplete games. Consistently, with an equal number of wins in matches, KB was almost always the same. That's why I "pushed" it further down the list.
